Abstract: PROBLEM TO BE SOLVED: To restrict a defect caused by fixing and to obtain improved printing quality for different kinds of media by providing a sensor constituted to generate a signal expressing the qualitative characteristic of the medium and adjusting a fixing parameter in response to the signal. SOLUTION: The sensor monitors the medium in order to control a fixing mechanism. Namely, the sensor decides or monitors the qualitative characteristic of the medium and outputs a characteristic signal expressing the qualitative characteristic thereof to an adjusting circuit 70. A control circuit 30 receives the characteristic signal generated from the sensor and controls the adjustment of the fixing parameter of the fixing mechanism in response to the signal. Then, the sensor monitors ambient conditions such as temperature and humidity and the circuit 30 monitors the medium and controls the adjustment of the fixing parameter in response to the monitoring of the ambient conditions. Furthermore, the circuit 30 monitors the fixing parameter such as fixing temperature and controls a fixing roller in response to the monitoring by using a fixing mechanism controller 74.

Title: Current conduction controller for inductive load
Inventor: HONDA TAKAYOSHI
IPC: G05F1/56
Filed: 2000-07-06
Abstract: PROBLEM TO BE SOLVED: To control load currents even when a power supply voltage fluctuates while ensuring current control precision in a device for controlling the currents of an inductive load by duty ratio. SOLUTION: A controlling duty ratio is calculated so that load current (i) can be turned to target current by a control circuit 10, and a switching element Tr0 arranged on a conducting path to a linear solenoid L0 is driven by duty ratio according to the controlling duty ratio. A load resistance switching circuit 20 capable of switching voltage drop quantity (resistance value) is arranged on the conducting path to the linear solenoid L0, and the resistance value of the load resistance switching circuit 20 is controlled so that the voltage drop quantity can be increased according as the controlling duty ratio is made larger (or a power supply voltage +B is made higher).  Thus, it is possible to prevent a voltage to be applied to the linear solenoid L0 from being largely changed according as the power supply voltage +B fluctuates, and to increase a current controllable power supply voltage range without decreasing the resolution of the current control.
